FEED IVIECHANISM FOR WEIGHING-lViACHINES.

SPECIFICATION forming part of Letters Patent No. 470,146, dated March 1,1892.

Application filed April 29, 1891- i770 a/ZZ whom t may con/cern:

Be it known that 1, HENRY E. SMYSER, of the city and county ofPhiladelphia, State of Pennsylvania, have invented a certain new anduseful Improved Feed Mechanism for NVeighing-lvfachines, of which thefollowing is a true and exact description, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates to weighing-machines of the general character shownand described in my patents Nos. 449,275 and 449,276, of March 31, 1891,but more particularly to the improved Weighing mechanism described andclaimed in my pending application led April 15, 1891, Serial No.389,030, in which said application a series of stationary scale-pans arecharged seriafim by a measure which is alternately filled and emptiedinto the differ! ent pans of the series. The object of my presentinvention is to simplify the said apparatus and increase its feed byproviding means for simultaneously charging all the scale-pans of l theseries.

The nature of my invention will be best understood as described inconnection with the drawings in Which it is illustrated, and the novelfeatures which I desire to protect are hereinafter clearly set forth inthe claims, reference being now had to the drawings, in Which- Figure 1is an elevation of a part of an automatic weighing-machine, showing myimprovement; Fig. 2, a plan view of the same, and Fig. 3 a plan view onthe section-line xx of Fig. 1.

A is a hopper through which the material to be weighed is fed to themachine. At the bottom of the hopper and forming a continuation of it isthe chute B, having brushes or Scrapers B on its front and rear edgesand, as shown, an opening B2 at its end.

C is a box or platform situated beneath the chute B and having a bottomO', through which a series of openings C2 are formed in a line lying infront of the chute B. The openings 02 correspond in number to thescalepans of the machine.

D is a reciprocating box resting on the platform C and having a motionfrom a point be- Serial No. 391,020. (No model.)

neath the chute B to a point over the openings C2. The box D is dividedinto a series of measuring-chambers D', the divisional partitions beingso placed that one of such chambers will register with each one of theopenings C2.

D2 indicate extensions from the bottom of box D to increase the bearingof the same on the platform C', upon which it slides.

E isa plate extending out from the back of the box D and having, asshown, a series of tongues E', which extend down into each of themeasuring-boxes D', said tongues serving the purpose of an adjustableside to the box or compartments by which its contents can be regulated.The movable sides are adjusted by means of the screw E3, the end ofwhich is connected with the back of the box D and upon which is a nutE2, said nut being attached to the plate E. The desired reciprocating'motion is given to the box D by means of the rod F, 'the lever F F3,pivoted at F2, and the cam F4, with which the end of lever-arm F3 :isengaged.

I I, Fig. 1, indicate scale-pans, of which there may be any desirednumber, preferably arranged in a circle and at equal distances apart.Above each scale-pan and opening into it is a chute H, the tops of saidchutes being connected byconduits G, each with one of the openings C2 inthe platform O.

The operation of the machine is of the simplest kind. The measuring-boxis moved so as to open to the hopper A-g-that is, in the design shownthe box D is drawn back until it is directly beneath the chute B. Wheneach compartment of the box is filled, the box is moved forward to theposition shown in Fig. l, the brush B sweeping off the ma-v terial levelwith its top, and the plate E closing the mouth of chute B when the boxis moved away from under it. As soon as the series ofmeasuring-compartments register with the openings C2 their contents fallout into the said openings and pass through conduits G and chutes H tothe series of scalepans I.

The additional or supplemental feed to the scale-pans can be effected inany of the Wellknown ways-such, for instance, as is shown in my patentsof March 31, before mentioned.

In the drawings I have indicated a feed-box K, supplied by chute J fromthe hopper A, said chute connecting with the hopper through the openingB2; butI have not thoughtit nec- 5 essary or advisable to illustrate themechanism by which the feed-box K is made to supply the differentscale-pans with a regulated supply of material, because such mechanismforms no part of my present invention and is fully described and shownin my former patents and application.

The essential and important feature of my present invention lies simplyin the provision of a series of measuring-boxes with means for fillingthe same and means for intermittently connecting each measuring box orcompartment, With one of the series of scale-pans, so that said pans canbe supplied with measured quantity of material simultaneously, insteadof receiving such measured quantities scriatm.

Having now described my invention, what I claim as new, and desire tosecure by Iletcombination, with a series of scale-pans, of a series ofchutes leading to the respective pans, a corresponding series ofmeasures, a supplyhopper, and means for actuating the 1neasures, asdescribed, and so that they shall alternately communicate with thesupply-hopper and the chutes.

2. In an automatic Weighing-machine, the combination, with a series ofscale-pans, of a series of chut-es leading to the respective pans, areciprocating box divided into measuringcompartments corresponding tothe chute series, a supply-hopper arranged above the box, a platform tosupport and guide the box having at one end a series of holescorresponding to the divisions of the box and connecting to the chuteseries, and mechanism arranged to actuate the box, moving it to and froma position beneath the hopper to and from a position over theholes inthe platform.

H. E. SMYSER.
